have a diameter of 200 microns. The blood-vessels have a
characteristic distribution. The Renal Artery passes through the
Hilus and enters the Sinus, where it divides into a number of
branches, of which the greater number supply the anterior pyramids,
and the anterior portions of the posterior pyramids. The branches
that go to the anterior pyramids carry the greater part of this
blood. The rest of the kidney is supplied by the posterior
branches. The branch that supplies each pole, derived from the
anterior division, divides into an'.erior, middle and pos V10.

terior branches, which are in no way united. The trunks pass up
through the columns of Bertini, where small branches are given off
to the vessels and tissues, as the InTerlobar Branches. These
branches pass to the boundary zone, where they arch between the
cortex and medulla, forming the Arterial Arches, or Arcade. From
the cortical side of the arch, the Cortical, or Interlobular,
arteries are sent towards the capsule; from these, small
arterioles, Afferent, pass to the Malpighian corpuscles, enter and
form several smaller branches, each of which breaks into a
capillary tuft From this, it will be seen that the Malpighian tuft
consists of several bunches of capillaries. Each capillary group is
separate, and the vessels unite to form arterioles that leave the
tuft as a single vessel, the Efferent arteriole. The blood is still
arterial. The Efferent arterioles soon form Dense Plexuses Of
Capillaries around the...
